The /etc/syslog.conf is unmodified which means the security.* facility is written to /var/log/security file. This is how its intended to work. When this same ipmon_flags=3D"-DsL security" statement is added to the vnet= jails rc.conf alone with the normal ipfilter statements the desired host behavior= is NOT occurring in the vnet jail. What is happening is the vnet jails ipfilter log records are being inserted into the hosts /var/log/security file. This is an error. Beyond that this i= s a security violation of the security intent of vnet jails as a whole. The vnet jails ipmon needs to be fixed to enforce the option flags in the v= net jails rc.conf ipmon_flags=3D"-DsL security" statement so the ipmon log reco= rds are written to the /var/log/security file with in the running vnet jail. FYI: This also occurs with ipfw. But ipfw has an un-documented statement firewall_logif=3D"YES" which when used in the vnet jails rc.conf will cause= the ipfw log records to be written to the vnet jails /var/log/security file. You may want to look at it for idea on how to fix ipfilter ipmon. --=20 You are receiving this mail because: You are the assignee for the bug.=
